To all whom it may concern:

Be itknown that I, HENRY A. WISE Wooo, a citizenlofrthe United States, residing at N cw York, in the county of New York and State of New York, have invented a new and useful Machine for Cooling Stereotypeljlates, of which the following 18 a specifica- UQB.

This is a division of my pending applica tion for patent for a machine for finishing and cool ng stereotype plates, Serial No. 11110343, filed A ril 6,1906.

'I his inventiog relates to the preparation lates for printing, and espe- =-ially to a coo ing machine designed to take MP8 of the product of several casting boxes.

Amohg the objects of the invention,

broadly stated, is the provision of means for receiving articles or costs, especially curved stereotype rinting plates, as they emerge nism, feeding t em, cooling them and auto? n aticallysetting into. operation the several. parts of the machine chiefly by the motion. of the plates themselves.'-

In order to provide a simple feed I have so constructed the machine. as toniake use of the force of gravity for this purpose.

lVliile. it isto be understood that the'prinriples ofin invention are applicable to the linishin 0 several different kinds of articles. I plied .to the finishing st reoty e plates. "Reference is to be had to the accompanyin which-,c lgure I is in side elevation of a machine and cooling of curved constructed in accordance with the priucipics of my invention. y I F isa phtn of a portion thereof. parts pp ri g in S on, and

For an ideagof the general nature of the invention, reference is to be had to Fig. 1 which shows a frgime a provided with an in vnrrying'steresectional view on the line 33 otyp'c plates.

The machineis intended to be used chiefly in conjunctiouwibh a plurality of casting boxes, the product of which is placed by handor oth ivyiselon the upper end of the rui yvay a. "Tiese plates then move by Specification of Letters Patent.

gravity down the run-Way to finishing mechanism (not shown) by which their edges are first finished, then they enter another part c of the finishing mechanism in whichtheir interior surfaces "are shaved by a shaving blade Z). From this point they pass to a-cooler d and from that they move out on a table c from which they are then removed by hand or otherwise.

It is to observed that on account of the incline of the run-way and on account of the fact that it is provided with antifriction devices shown as in the form of a series of rollers 25, no positive feedin mechanism and no driving device for feedin the plates or other blanks is necessary. he incline of the bed is such that the plates are readily fed down by gravity when they rest freely on therollcrs and if the rollers are held in stationery position and, prevented from rotatin the plates are held and do not slide along the stationary surfaces of the rollers.

When the plate is released from the shaver 1;, c it runs out on the rollers helovv it and This cooler inthe form having a chamber for receiving the plates or other articles to be operated upon. y The outer Wall of the shell is provided with a passage 3 having an water or other cool: in fluid upon the outside of the plate. Inside the chamber having a. similar as'sage 5 'for providing for coolin the inside of the stereotype plate.

into the cooler :1.

Both ,tiese passages are connected by pipes 6 with a supply pipe 7 having a valve or cook 8. With this cock is connected an arm 9, link 10 and lever 11. This lever is pivoted on the frame and is provided with dogs 12 located normally in the path of motion of a plate entering the cooler. \Vhen the plate asses along the rollers and engages these dogs, it moves the lever in opposition to the force of a spring 13 which normally holds the valve 8 closed. This opens the valveso as to permit the cooling fluid to enter both passages 3 and 5 and cool both sides of the plate as long as the plate ismains in :cnga ement with the dogs.

It is desire le to leave the plate in the cooler as long a time as is necessary for the finishing of a plate in the shaver, conseis also located a plate -l frame and is provided with dogs 19 quently Ihave provided movable stops 14, preferably pivotall mounted on a shaft 15. An arm 16 is provi ed for swingingthe stops and this arm is connected by a lin 17 with a lever 18.

This lever is pivotally mounted on the rojecting into the path of an incoming p ate. A spring 20 normally holds these parts 111 the position shown In Fig. 1. When the dogs 19 are depressed by an incomin plate resting on them, the stops 14 are a so de pressed. The lever moves in opposition to the spring 20, and the plate in the cooler slides out on the table 6 against a stationar stop 21. It will be seen, therefore, that one plate remains in the cooler until another plate is finished and delivered into a position to enter the cooler. If the operator de sires to allow a plate to leave the cooler before another plate is delivered to it or if no more plates are to be delivered, e can manipulate the lever 18 by a hand-operated slide The water or other cooling fluid applied to the plates is collected in a receptacle 23 and may be discharged in any desired way.

The broad combination of a stereotype printing plate finishing mechanism and a cooling device is claimed in my ori inal application previously referred to, his divisional application being filed in pursuance to a requirement of the Patent ()ilice that the details of the cooling mechanism be specifically claimed in a divisional application.
